EGG-TESTING nnvrcn.

, Application filed October 31, 1924. Serial No. 746,975.

2 '0 whom it concern:

Be itknown thatI, EMIL hirttnn, a citig zen of theUni-ted-States,residing at North Haledon, in the countyof Passaic and'State of NewJersey, have invented certain new and useful Improvements in Egg-TestingDevices,'of which the following'i'sa specifi cationpq v In'testing eggsduring incubation there is at present no satisfactory means fordetel-mining with accuracy from time to time theprogress of theincubation. The work the butt-end. up so that .the observer can determine the position on each reading of the level of the liquid contentsofthe egg, and

it is not attended with any Qapproachto the of the liquid contents ofthe egg may be observed by holding it butt-end up before a light; andits object is therefore to provide means whereby the level of the liquidcontents of an egg may at any time be calculated to a nicety, Whetherduring the process of artificial incubation or for the purpose ofdetermining the age of the egg,

as in candling.

Tothis end I have in the best form of my invention provided a card witha recess to receive the butt of the egg and adapted to be placed withthe egg, having its buttend up and in'the recess, between theobserverand a suitable source of light, the

gin of the recess. As indicated, this is a statement of the best form ofmy invention; but broadly, the invention consists in a gaging bodyhaving an egg receiving recess and gagging portions arranged atintervals along the marg n of the recessand through which the passage oflight is obstructed in different degree from what it is by the portionsof the body intervening between-the gaging portions, for while it isbest to have the gaging 1 portions less resistant to light than theremainder of the body so as to protect the eyes of the observer fromthelight, thisis not indispensable Further, it beingnew so far as I amaware to provide a card or other sheet-like body with a recess to re- 7ceive the egg andgaging portions arranged at intervals along the marginof the recess, I broadly claimsuch abody for use in testing eggs. 7 I

The accompanying drawing shows my invention,

In Fig. 1 in elevation, an egg being shown in position in the recess ofthe testing de vice or body;

In'Fig. 2 in vertical section; and

In Fig. 3 in elevation, this view showing a modification of theinvention.

In thedrawing, Figs. 1and2, ai is a card formed with a recess 7) whichis here located in one side or edge of the card. 'On lines (which may infact actually appear on the card, as shown) which traverse the recessare formed perforations 0; usually there will be one or more of theseperforations to a line on each side of the recess. The lines are spacedapart suitable distances, as

shown, and for convenience there may be provided in connection with themindices,

such as 5, 10, 15, 18 and'21. The egg is placed with its butt end in therecess-and then the card and egg are held between the observer and asuitable source of light. The card in this case is opaque'or at leastmore resistent to the passage of light there through than theperforations 0 forming its gaging positions. Thus the said gagingportions stand out, and by noting with which one of them-theliquid-levcl in the egg corresponds the observer can determine quicklyand accurately the progress of the incu-' bation and govern thecontinuance thereof accordingly. The line 5 indicates 5 days ofincubation; 10, 10 days, etc. card being opaque except for gagingportions arranged at intervals along the mar-' The card may be madeimperforate, as shown in Flg. 3, where {d lsa card of cellulold, forexample, the gaging portions c being here attenuated narrow parallelstrips what I claim is new and desire to secure.

by Letters Patent is: r

1. A device for use in testing eggsconsisting of a gaging body having anegg-re ceiving recess and adapted to be placed with the egg, having itsbutt-end up and in the recess, between the observer and a suitablesource of light, said body having gaging portions arranged at intervalsalong the margin of the recess and through which the passage of light isobstructed in different degree from what it is by the portions of thebody intervening between the gaging portions.

2. A device for use in testing eggs consisting of a gaging body havingan egg-receiving recess and adapted to be placed with the egg, havingits butt-end up and in the recess, between the observer and a suitablesource of light, said body having gaging portions arranged at intervalsalong the margin of the recess and through which the passage of light isobstructed in less degree from what it is by the portions of the bodyintervening between the gaging portions.

3. A device for use in testing eggs consisting of a sheet-like bodyhaving an eggreceiving recess and adapted to be placed with the egg,having its butt-end up and in the recess, betweenthe observer and asuitable source of light, said body having gaging portions arranged atintervals along the margin of the recess.

In testimony whereof I affix my signature.
